the Ga-Li complex. A Ga-Li-linked-BINOL complex promoted the epoxide opening reaction in up to 96% enantiomeric excess (ee). Second, based on the X-ray structural information of the Ga-Li-linked-BINOL complex, we designed a more stable lanthanide linked-BINOL complex. An air-stable, storable, and reusableLa-linked-BINOLcomplex promoted the Michaelreaction in up to >99% ee. The catalyst activity remained
